My 2 bettas sam and angel that are in my glass split tank are constantly flaring at eachother like they will take a bit of a break ect but most of the time they just flare flare flare... I have had them a couple months and yea its starting to worrie me now cause around where sams gills are the scales look a bit raised like he has flared to much... I dont know if that can happen is why im asking all of yous. Hope you can help :)Oh by the way i dont have something i can put in the tank to stop them from seeing eachother planto get a plastic thingo from the hardware store down the line but yea.. thought i should add that.

Yes this can be very harmful, not only physically but it will also stress them out a great deal. This can shorten their lifespan a lot and make them suseptable to illness. Try to cover the space with something like opaque glass or lots of plants and ornaments.

Thank you ill look into something i can put in there, as far as stress i think there fine, they both compete in bubble nests and today i woke up and like i have never seen such big bubble nests from either of them lol

It may not look like they Are stressed out but they are. I know my sorority girls didn't look stressed when I put them in for the first time, but there is no doubt they were. But as long as you don't delay the change in scenery for any longer than nessasary, they will be fine :)

I have the same problem with Caligula and Gyger. I tried blocking the divider with plants but they just squeeze inbetween the plants and the divider and keep flaring.

Sigh... i know what u mean...came home from going out for a drive for a min and sam was stuck inbetween the 2 dividers.... he is such a terd.... which yet again brings me back to the *i spit on people that say fish only have a 5 sec memory..* if my fish had a 5 sec memory they wouldnt fight this divider soo fkin hard lol!gonna have to serch for a different kind of divider...

IMO...no. My bettas are in constant sight of each other...IMO they need social interaction. I have info from an IBC judge, transhipper, and breeder that goes to show being visually seperated is bad for them. It's like putting you in a room with a couch, food when you're hungry, water when you're thirsty, etc. but you don't see humans...after awhile you won't know what to do when you see another person. I can post a link to my thread on the experiment that Linda did.

How long have you had them like that?
I have had my bettas for a couple months and at this point they do there own thing then one will arch up and they go at it for a bit then back to what ever they where doing, im just worried casue it might be causing stress on there gills or something having them flaring so much. does ur bettas flare alll the time ect aswell or?
